The recent changes in 4.9 to mandate USB buffers be heap allocated broke this driver, which was allocating the buffers on the stack. This resulted in the device failing at initialization. Introduce dedicated send/receive buffers as part of the state structure, and add a mutex to protect access to them. Note: we also had to tweak the API to mxl111sf_ctrl_msg to pass the pointer to the state struct rather than the device, since we need it inside the function to access the buffers and the mutex. This patch adjusts the callers to match the API change.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
